Abstract
In this article are presented the results of the research about strengthening piece avulsion from the metallic matrix of Al and Al-50%Zn that are obtained after the traction break. The results are legitimated about the aluminum carbide from the matrix- strengthening piece interface. Composites are obtained by liquid forging. And the strengthening piece is unidirectional aligned. The temperatures for the premolding preparation were about 20oC, 600oC and 900oC. During the heating and the manipulations, it worked continually under the neuter argon atmosphere to protect these highly reactivity oxygen fibers. Measurements were made on test-pieces tear to pieces by traction break into longitudinal sense of strengthening piece. After the test, surface was covered with a silver layer, witch was dreg from steam phase. Fibers were included into a transparent resin and after the splitting extraction length measurement was made. In this paper are presented fibers avulsions from aluminum matrix (maximum quantity of aluminum carbide from strengthening piece interface have the result of an strong adhesion and therefore fibers will tear into matrix breaking section plan) respectively 50% Zn alloy aluminum matrix (Aluminum carbide cause an medium adhesion into interface and fibers tears into pieces according with histogram). Also are presented SEM microscopy of the Al matrix samples and 50%Zn alloy aluminum matrix.
